MPROVEMENT IN MACHINES FOR MAKING CORDAGE.

Specification forming part of Letters Patent N o. ,b25, dated March 23,1852.

To all whom t may concern:

Be it known that I, WILLIAM J osLIN, of lVaterford, in the county ofSaratoga and State of New York, have invented certain new and usefulImprovements in Machinery for Making Cordage, which is described asfollows, reference being had to the annexed drawings of the same, makingpart of this specification.

-Figure l is aside elevation of the machine. Fig. '2 is a top Viewshowing the machine as in operation. Fig. 3 is a sectional view on theline c d of Fig. 2, showing the exterior of the capstans for drawing thestrand. Fig. 4 is a sectional view on the line a b of Fig. 2, showingthe interior of the capstans. Fig. 5V are two halves of adrawing-capstan. Fig. 6 is an end view showing the pulley on the end ofthe shaft turning in the hollow journal of the nier, and the pulley onthe end of the fan, also the endless band around the same. The arrowsshow the direction of the movement of the several rotating portions ofthe machine.

As the improvements which I have made in the rope-making machine forwhichl now solicit Letters Patent relate to two parts onlyviz., thedrag-fan and the split capstans-I shall make the description of therest. of the machine very brief.

A is the frame; B, spools containing the yarn to be laid and twistedinto a strand; C, perforated guideplate through which the yarns pass; D,tube; E, hollow journal of the flier; F F, drawing-capstans gearedtogether by the gears G G, so as to bring the larger diameter of one ofthe capstans opposite the smaller diameter of the other; lil,reciprocating guide for laying the strand evenly upon the spool; I,right-and-left screw for moving the guide to the right and to ythe left;J K L, gears for turning said screw, M, spool for winding the strand; R,the iiier; S, stationary cog-wheel, around which the cog-wheel T,attached to the Iiier, revolves for putting in motion the bevelcogwheels U V, and pinion W', engaged with one of the cog-wheels G forrevolving the drawing-capstans; X, drum or pulley fixed to the end ofthe ilier, around which passes a band Y, leading to the drivingpower.

The following portion of the description relates to that part of themachine which I claim as new: N O P Q, gears for turning the spool orbobbin, said bobbin having two mo tions, one over endwise with the flierand the other on its own axis. e is a revolving shaft passing throughthe hollow journal or bearing of the flier, having on its inner end thepinion Q, which turns with the shaft e independently of the flier, and alarge pulley f on its outer end, around which passes an endless band g,leading around a small pulley h on the end of shaft i of a fang` 7c,made in two parts, so as to be capable of folding in order to diminishor increase the size of the fan when required to diminish or increasethe resistance of the air. Z are the boxes or bearings of the axle ofthe fan.

The drawingcapstans F are divided at the center into two equal parts FF, which are attached to the face of the gear-wheels G G by dowels orpins projecting from the face of the gear-wheels and enteringcorresponding holes in the end of the capstans, said sections or partsof the capstans being con lined to the gears by clamp-nuts 'n n, screwedupon the shafts s s of the gear-wheels.

i The reason for dividing the capstans at their diameter is to enablethe operator to change .the capstans at pleasure for larger or smallerdiameter ones, according to the kind of strand to be drawn, without thenecessity of deranging or removing any part of the machinery in order toeffect the change, and the two capstans, (forming a double one), projecting as described from the wheels G G, and made (each one) of taperingor diminishing diameterthe large diameter of the one opposite the smalldiameter of the other-serve, without undue stretch, most efliciently tofeed or draw the strand, which, in commencing its wind over the largediameter of the iirst capstan, has a tendency and gradually slips or`slides toward the smaller end of the same, thereby feeding the secondcapstan over its largest diameter, and as the strand inclines toward thesmaller diameter of it (the second capstan) the feed is similarlyperformed or facilitated for supply to the reciprocating guide H; also,the two capstans so constructed, arranged, and operating maintain thestrand in a straight line, or nearly so, through the machine.

The fan, before referred to as a drag or I blades, which increasingresistance'in being take-up,aets in the following manner: rlhe Velocityof the flier always being the same, and the draft On the strand ofnecessity constantly increasing as the cop wound on the bobbin Menlarges in diameter, it becomes necessary to obviate theincrease ofstrain On the strand to which it is liable as the cop enlarges. The i'anaccomplishes this, as will be evident from the following explanation,aecompanied by reference to the drawings: The flier It as it rotates isthe driver of the fan through the pinions N O I), connected with theiiier and bobbin, and pinion Q on the shaft e, operating the fan. Now asthe cop begins to Wind upon the bobbin the pinion Q but slowly moves oris almost stationary, but as the cop enlarges in diameter on the bobbinthe velocity of the latter On its axis will necessarily be diminished asthe leverage it has to Wind at becomes greater, and during suchenlargement of the cop and diminution in speed of the bobbin the motionof the fan is being uniformly accelerated thereby, giving increasedresistance of the atmosphere to its felt or thrown through the pinions NO I) Q on the bobbin checks any tendency to increase Of strain on thestrand as the cop enlarges, the pinion P, in traveling round and beinggeared with Q, effecting this result.

The fan-blades, as before observed, may be or are made in halves, so astO lap, for the purpose of increasing or diminishing the area ofresistance inthe fan, to suit different kinds of work, or any otherinode of adjusting the strength of the fan may be adopted.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The application of the fanj k, in combination with the pulleysf h, beltg, gears N O P Q, and bobbin M as a drag or take-up, as above described.

In testimony whereof I have hereunto signed my name before twosubscribing Witnesses.
